Fusion Bonded Epoxy Tank for Beverage Wastewater: Ideal for containing high-sugar and low-pH liquid waste

The global beverage industry, spanning breweries, distilleries, soft drink bottlers, and juice manufacturers, generates significant volumes of beverage wastewater. This effluent is characterized by two demanding features: extremely high-sugar content (high BOD/COD) and a tendency toward low-pH liquid waste due to the rapid fermentation of sugars and the use of acidic cleaning agents. These factors create a highly corrosive environment that poses a constant threat to containment integrity. Therefore, the infrastructure must be ideal for containing this specific combination of chemical stressors. The Fusion Bonded Epoxy (FBE) Tank is engineered precisely for this environment. At Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), we utilize FBE technology to deliver robust, high-performance bolted steel tanks that ensure the secure, long-term management of high-acid, high-organic beverage waste streams.

The Corrosive Nature of Beverage Effluent

The treatment of beverage wastewater requires containment that can withstand rapid chemical changes and continuous acidic attack:

Low-pH Acidity from Fermentation: Residual sugars and carbohydrates in the effluent rapidly ferment, producing lactic acid, acetic acid, and other organic acids. This process drives the pH down, creating a low-pH liquid waste that aggressively attacks unprotected steel and concrete.

High Organic Load and Viscosity: The high-sugar content results in high BOD and COD, which can create a dense, viscous effluent that places high loads on the tank structure and demands a non-stick internal surface to prevent fouling and microbial adhesion.

Chemical Clean-in-Place (CIP) Exposure: Breweries and bottling plants rely on frequent caustic or acidic washdowns to maintain hygiene. The containment tank must be able to withstand the severe and rapid pH swings caused by these cleaning cycles without coating failure.

Temperature Fluctuation: Effluent can be discharged at varying temperatures from pasteurization or cooling processes. These temperature variations can stress linings, leading to cracking or delamination, which allows the corrosive effluent to attack the steel substrate.

Anaerobic Treatment Demands: Beverage wastewater is often treated using high-rate anaerobic digestion (AD) due to its high organic load. The corrosive byproducts of AD, particularly hydrogen sulfide (H2​S), demand specialized, acid-resistant containment.

The infrastructure solution must be fundamentally ideal for containing high acidity over a sustained period to ensure operational longevity.

The FBE Solution: Ideal for Containing High-Sugar and Low-pH Waste

Center Enamel’s Fusion Bonded Epoxy Bolted Steel Tanks are specifically engineered to endure the specific high-acid, high-load conditions of the beverage industry, proving to be ideal for containing high-sugar and low-pH liquid waste:

Superior Acid Resistance: The FBE coating is a dense, thermoset polymer that is molecularly bonded to the steel substrate. This inert, high-performance barrier provides uncompromising resistance to the continuous exposure from low-pH organic acids and is built to protect the steel from the corrosive effects of fermented beverage wastewater.

Inertness for Process Stability: The FBE coating is non-toxic and non-leaching, ensuring that the tank material does not inhibit the delicate microbial balance necessary for effective biological treatment or anaerobic digestion, which is crucial for maximizing biogas yield in high-sugar environments.

Hygienic and Anti-Fouling Surface: The smooth, non-porous finish, achieved through meticulous factory application, is a key feature in the beverage sector. It actively resists the adherence of sticky sugars, proteins, and biofilm, simplifying cleaning and reducing the operational costs associated with fouling and sludge buildup.

Structural Integrity for Digestion: For anaerobic digestion, FBE tanks are built from high-strength steel to handle the immense hydrostatic loads and internal pressures generated by gas-tight reactors, guaranteeing a secure, ideal containment vessel for the high organic content of the waste.

Modular and Rapid Construction: The bolted design enables rapid construction on site, which is vital for beverage plants with tight expansion schedules. This speed minimizes disruption and allows plants to quickly meet regulatory requirements for increased treatment capacity.

Product Industry Application: FBE Tanks in Beverage Wastewater Management

The chemical resilience and inertness of FBE tanks make them indispensable across the highly organic and acidic treatment trains utilized in breweries, wineries, and bottling plants:

Anaerobic Digestion (AD) Reactors: Due to the high high-sugar content, FBE tanks are primarily used as robust, corrosion-resistant digester vessels, ensuring safe and efficient conversion of organic waste into valuable biogas energy.

Effluent Equalization and pH Balancing: Tanks are deployed as essential equalization basins to stabilize the flow, temperature, and highly variable low-pH liquid waste before it enters sensitive biological treatment stages, protecting the entire downstream process.

Clean-in-Place (CIP) Holding/Neutralization: FBE tanks are crucial for securely holding or neutralizing the strong acidic or caustic cleaning agents used in bottling and brewing, preventing these corrosive chemicals from overwhelming the main treatment system.

Aeration Basins (Post-AD): In the final polishing stage, FBE tanks are used as aeration basins, providing a reliable, inert platform for the final reduction of BOD/COD before compliant discharge.

Sludge Thickeners and Storage: The tanks are used for the secure storage of dense, acidic sludge generated during clarification and treatment, where corrosion resistance at the tank base is paramount.
